Abstract:

Partial range of focus (ROF) intraocular lenses (IOL) offer excellent distance and intermediate visual acuity, but usually limited distance-corrected near visual acuity (DCNVA). We evaluated the characteristics of eyes implanted with two specific ROF IOL and very good DCNVA. We conducted a prospective, observational, cross-sectional study. Patients implanted with a ROF IOL were visited 1-3 months after uneventful phacoemulsification. We determined mono/binocular, corrected/uncorrected visual acuities (VA) at far, intermediate and near distance; photopic pupil diameter, corneal asphericity, aberrations (RMS_HOA, Z_4- 0), and axial length (Pentacam^® AXL Wave; Oculus, Germany); and implanted IOL power. Monocular DCNVA was stratified in tertiles, with eyes in the first (better DCNVA) compared to the others (standard DCNVA). Univariate and multivariate generalized estimating equations models were used to compare the features of both groups. One-hundred eyes from 50 patients (mean age 69.0 years [SD 8.7], 66.0% female) were enrolled. Monocular distance logMAR VA was 0.00 (0.04) and DCNVA was 0.37 (0.15). Only younger age (66.4 vs. 71.0 years), smaller pupil (2.81 vs. 3.04 mm), and better distance VA (0.00 vs. 0.02 logMAR) were associated with better DCNVA. Therefore, a better distance-corrected VA, smaller photopic pupil diameter and younger age favored better DCNVA with the tested ROF IOL.

Focusing of Light in the Eye

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

$Influence of Earth's Curvature and Atmospheric Refraction on Leveling$ 01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance. Over a...
